Integration of modern genomics tools with traditional breeding approaches will transform crop improvement in Rosaceae, significantly improving profitability of U.S. rosaceous crop industries and contributing to increased consumption and enjoyment of these fruit, nut and floral products. We will create a dynamic, sustained program in research, infrastructure establishment, training, and outreach for developing and applying marker-assisted breeding (MAB) based on improved knowledge of industry value and consumer preferences to accelerate and increase the efficiency of rosaceous cultivar release and successful cultivar adoption.
